Carbon Cycle steps and def
What is key element in living things found in ocean The ways its recycled are 1. plants and animals 2. geochemical ocean/volcanoes 3. humans-fossil fuels
200
What is carrying capacity?
What is the greatest number of organisms an area can have
300
What are the 6 levels of organization??
What is species -> population -> community -> ecosystem -> biome -> biosphere
300
What are the definitions of the three community interactions: competition, predation, and symbiosis.
Competition: trying to use the same resources Predation: one organism eats another Symbiosis: 2 organisms interact with each other with benefits.
300
Lush perennial grass, resistant shrubs, grasses, and herbs, badgers, bears, rabbits, prarie dogs, owls, warm to hot summers, cold winters, moderate precipitation
What is temperate grassland
300
Nitrogen cylce def and steps
What is the need for protein. found in atmosphere, dead things, ocean, fertilizers. How? Fixation and dentrification
300
What is the difference between exponetial and logistic growth?
What is exponential are perfect conditions and a J shaped graph, and logistic are realistic conditions as population growth slows or stops with an S graph
400
What's the difference between a food chain and a food web? What is a trophic level?
What is a food web is more complex and is made up of many food chains,and a trophic level is each step or level in a chain/web.
400
What are the 3 types of symbiosis and what are the interactions between the animals?
What is 1. mutualism -- both benefit 2. commensalism -- one benefits, one neutral 3. parasitism -- one benefits, one hurt
400

400
In which cycle is photosynthesis and cell respiration used?
What is carbon
400
What is a limiting factor?
What is Something that limits the growth of a population like competition
500
What are the 3 Ecological Pyramids and the ratio for them all?
What is the energy, biomass, and pyramid of numbers, each having a 10% energy or mass loss per level.
500
What is ecological succesion? The difference bewteen primary and secondary succession?
What is a series of predictable changes that occur in a community over time. Primary succession is when there's no soil, like a volcano eruption, and secondary still has soil, like a forest fire.
500
Tall grasses, drought tolerant or fire resistant plants, lions, leopard, cheetah, zebra, giraffe, elepphant, warm temperatures, seasonal rainfall, frequent lightning fires
What is savanna
500
Atmospheric Nitrogen Fixation in the nitrogen cylce is created by what?
What is lightning
500
What is a density independent and density dependent factors?
Density independent factors are competition, parasitism and disease, and predation where the density doesn't matter, while density dependent the pop. is reduced no matter what like a flood or drought
